Hello,
while working on Windows and compiling with MSVC(1921), and using common windows headers, i couldn't compile while using Streams. This is due to the implementation of

inline auto max(Less&& less = Less())

and

inline auto min(Less&& less = Less())

in StreamTerminators.h.

min and max are already defined as macros

#define max(a,b)            (((a) > (b)) ? (a) : (b))

and

#define min(a,b)            (((a) < (b)) ? (a) : (b))

in minwindef.h.

I got it working by first, undefining, and at the end of the file, redefining min and max.
